SLDW-IDOWN DELIVERY.

Application filed August 11, 1927. Serial No. 212,29?.

rlhis invention relates to certain improvements in slow down mechanisms for handling' products from printing` machines.

ln certain classesof printing); mechanisms, and particularly in modern high speed web printing; machines Where the Web is cut into sheets, difficulty is experienced in accurately there is danger of the products smutting, and

diiificulty has been experienced with these deliveries from this and other causes.

lt is the especial object of the present invention to provide an improved slow down mechanism whereby the products are delivered to an intermediate transfer cylinder provided with foldingw avvs and operating; at the hinh speed of the press, this cylinder deliver- ,inn` the products to one or more delivery cylinders which run at a slower speed, these latter cylinders in turn delivering; the products, Where desired, to belts or the like.

A further object of the invention is to produce a construction in Which the products are `thus transferred. in which the parts shall be few in number and thus simple, and in which a very smooth and even delivery of the product from a high speed press is obtained.

lilith these and other obj cctsnot specilically referred to in view, the invention consists in certain novel parts. arrangements and combinations which Will be described in connection with the accompanying drawings and the novel features pointed out in the claims hereunto annexed.

In these draWinns,--

Figure 1 is a sectional side view of so much of the folder end of a high speed printing press as is necessary for an nnderstandinp,` of the invention, the parts being;` shown as delivering` to tivo deliveries;

Figure 2 is a more or less diagrammatic view, partly in section, of parts of the folding" and transfer cylinders. showing` the seqnence of operation when folding the product into the folding jaws and releasing it from the jaws;

Figure 8 is aview somewhat similar to Fiejure 2, shoivinp; more or less diagrammatically the sequence of operation When the i any usu al, construction, not shown.

product is delivered from the transfer cylinder to the delivery cylinder and from the latter to a carrier, such as belts;

Figure d is a top plan view, partly in scction, of the parts shown in Fininfo 3, the view being taken on the broken line 3 3 of that ligure and looking in the direction of arrow Ll, and

Figure 5 is a detail. view illustrating; a modification in folding jaws which may be employed under some circumstances, if desired.

Referring now to these drawings, a product, indicated by the letter l), is there illustrated. '.lhis product is a cut product, cut by suitable cuttinn` mechanism and comino from a high speed rotary printing; machine. The structure of the cutting' mechanism and the printing machine is not shown, it beinp; unnecessary for a clear understanding of the invention.

ln the particular' mechanism selected to illustrate the invention. the product to be forwarded may be a single product or a. collected product. The product will, however, be folded and, as shown, there is provided a folding and collectingI cylinder l. mounted on a shaft 2 suitably supported in side frames of 'lllhi s cylinder is provided with the usual collect. devices, shown in the form of loup,l 2strippers li, (3 and short grrippers 7, 8. these ggrippcrs being' mounted on the usual gripper shafts Si and operated by operating arms l0 from cams not illustrated. The cylinder l ic4 as shown, a three part collecting1 cvlin der oi? usual construction, and tivo sets of collecting: `o rippers are shown, it beine; understood that there is a third set, not illustrated. rlhi s cylinder is provided with tuelrine` blades ll. carried on a shaft 12 and operated in the usual manner by means of arms i3, from cams not illustrated, to fold off the product from the cylin der.`

This cylinder l runs at the high speed of the press. and cooiiierating with this cylinder l is a folding` off cylinder 14; mounted on a shaft 15 suitably supported in the side f ames before referred to. This cylinder is provided with a plurality of sets of folding' jaws, tivo such sets beingV shown, and the cylinder is one and one third the diameter of the collecting cylinder. The folding jaws are alilre in construction andthe operation and description of one will suffice for all.

Referring first to the construction shown lll] in Figures 1 to 4, there is shown a pair of pivoted jaw members 16, 17 mounted on shafts 1S, 19. These jaws are, as shown, provide-'d vwith wide gripping faces, between which the Yder and when the productis first talren it is held by the aws in a line radial to the cylinder. Cooperating with the jaws are sheet taking devices, shown in the form of grippers 24, these grippers being located closely adj acent the aws and arranged in sets widthwise of the cylinder, three grippers being shown in the drawing, one of these sets being provided for each of the folding jaws. These grippers are, as shown, arranged in advance of the jaws and while the productis held by the folding jaws it is pressed down by the grippers and, after the grippers are brought into engagement with the product, the jaws are released.

It will be observed that the grippers in pressing down the productbend t-he product into a right angle turn, where it is held by the V jaws, but when the jaws open this Vright angle bend is permitted to straighten out, so that the product when delivered from the transfer cylinder lies perfectly flat. This sequence of operation is shown in Figure 2. At position a the sheet has just been tucked into the gripper aws which `are closing on the sheet. As the jaws travel around with the cylinder in the direction of the arrow to position t), the grippers are opened to take the product, and at position c have taken the product, the jaws being closed in these positions. At posit-ion d, however, the jaws have opened, and the right angle bend formed in the product and indicated at e has straightened ont, and the product is now being carried under the control of the grippers. lf desired, a curved guide 25, shown in dotted lines in Figure 2, may be provided for the product after it is taken by the grippers.

From the transfer cylinder the product is taken to a delivery which runs at a lower speed than the collecting and transfer cylinders 1 and 14, before referred to. This delivery is shownas a pair of delivery cylinders 26, 27 mounted on shafts 28, 29 suitably supported in the side frames of the machine. Each side of the transfer cylinder coacts with one of these delivery cylinders to deliver a product thereto, and these delivery cylinders are run at a speed lower than that of the cylinder 14, in the particular instance illustrated this speed being one-half that of the latter cylinder. The cylinder 27 is provided with a set of sheet taking grippers 30 mounted on a shaft 31, thesevgrippers being opened and closed by a cam'roll 32 cooperating with a fixed cam The delivery cylinder 2G is also provided with grippers 34 on a .shaft 35 operated from al cam roll Sti, in turn controlled by a fixed cam similar to the cam 53. From the grippers 30 and 34 the product is delivered to any suitable delivery, shown as a travellingca rricr in the form of belts or tapes 37, strippers 3S being preferably provided at each delivery cylinder for stripping the product therefrom and insuring its delivery onto the tapes.

The grippers 30, 34 on the delivery cylinder, it will bc observed, referring to Figure 1, are shown arranged in oll'sct relation to the grippers 24 on the jaw cylinder 14, two grippers on the delivery cylinders being shown. The grippers 30, 34 are normally open to receive the product and they take the product from the grippers Q4 on the jaw cylinders at points ahead of the jaw cylimler grippers, as shown in Figure 3, the grippers 24 opening to release the product at the instant the. grippers 30, 34 ofthe delivery cylinders have taken the product. It will be understood that the grippers 24 and the grippers 3() are. provided in required numbers across the cylinders.

'lhe grippers 24 on the jaw cylinder are operated to open and close by a pair of cam rolls 39, 4() which cooperate with a cam 41, these cam rolls being carried on shafts 12, 13, these shafts being tied together by links All, this construction being the same for each set of grippers 24. 1n the best constructions, the folding jaws 16, 17 are preferably continuous throughout the length of the cylinder, except where they are cut out, as indicated at l15 (Figure 4), for the gripper supports yslt, so that an effective clamping surface for the grippers is provided.

In the construction shown in Figures 1 to 4a pair of folding jaws is shown. Under some circumstances it may be desirable to use a single rocking jaw which cooperates with a stationary abutment, and such a construction is shown in Figure 5, in which the jaw meehanism includes a rocking jaw 47 which clamps the product against a lxed abutment 4S formed in the wall of the cylinder 14.

The various parts may bc driven in any suitable manner, through a gear, indicated at 49, on the transfer cylinder 14 and gears 50, 51 on the shafts of the cylinders QG, 27.

l WYit-h the construction shown and described a very smooth even movement of the folded product from the high speed collecting mechanism to the slower speed delivery is etl'ccted, and a movement in which smutting and other injury to the product is avoided.
